1 The Nature and Explanatory Ambitions of Metaethics By Tristram McPherson (Ohio State University) and David Plunkett (Dartmouth College) Forthcoming in The Routledge Handbook of Metaethics (general introductory chapter for the handbook) Penultimate version of August 2016 Please quote and cite the final version once available Introduction. This volume introduces a wide range of important views, questions, and controversies in and about contemporary metaethics. It is natural to ask: What, if anything, connects this extraordinary range of discussions? This paper aims to answer this question by giving an account of metaethics that shows it to be a unified theoretical activity. According to this account, metaethics is a theoretical activity characterized by an explanatory goal. This goal is to explain how actual ethical thought and talk and what (if anything) that thought and talk is distinctively about fits into reality. We begin by introducing and developing this account, and illustrating it via discussion of a simple illustrative metaethical theory: simple subjectivism ( 1). We then explain important upshots of the characterization ( 2). Our account is novel and controversial, as is the status of metaethics as a theoretically fruitful project. We thus compare our account to competing characterizations of the field, and explain how our account permits us to address certain challenges to the theoretical significance of a distinctively metaethical project ( 3). In the conclusion ( 4), we explain why, given our account, one might think that metaethics matters, and explain how our account understands the history and future of self-conscious metaethical theorizing. As we will emphasize, we should expect new ways of approaching the explanatory project at the heart of metaethics to emerge in the coming years, as the tools and resources we have for tackling that project expand. Our hope is that by emphasizing the centrality of the explanatory project itself, rather than just focusing narrowly on the views that have been

2 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 2 developed so far by those engaged in that project, we can help encourage and facilitate the development of new questions, arguments, and views that help move the field forward. 1. The Proposal In the Introduction, we promised to argue that metaethics is a unified theoretical activity. To get a feel for this claim, consider the following three groups of questions: Group 1: -Is it good to be vegetarian? -When (if ever) is abortion ethically permissible? -How much should I give to charity? -Is assisted suicide ethically okay? Group 2: -Is it always ethically permissible to promote the best outcome? -Do facts about virtuous agents explain facts about right action? -Do the actual outcomes of an action typically explain whether it is right or wrong, or are the expected outcomes the ones that matter? Group 3: -What are we doing when we sincerely utter simple ethical sentences such as Killing innocents is wrong? Are we expressing beliefs about some subject matter? Or are we doing something else? -Are ethical judgments necessarily motivating? -Are there ethical facts? -Can armchair reflection provide ethical knowledge? - How does ethics relate to the kinds of facts that we study in the natural and social sciences? The questions in Group 1 are often regarded as core questions in applied ethics (or practical ethics or case ethics ). Those in Group 2 are often regarded as core questions in normative ethics (or systematic ethics or ethical theory ). And those in Group 3 are often regarded as core questions in metaethics. So we can sharpen our initial

3 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 3 question about what unifies metaethical discussion by asking: does it make sense to group the Group 3 questions (and others like them) together, in a way that excludes questions in Groups 1 and 2? And if so, why does that make sense? One reason it might make sense to group these questions together is that the groupings are sociologically significant. Certain people (e.g., a certain subset of professional philosophers) tend to group them together, and it could be useful to track these tendencies. However, we think that the Group 3 questions share a deeper theoretical unity. The first step towards seeing this unity is to notice that we can understand each of these questions as arising naturally in the context of very general attempts to explain central apparent features of ethical thought and talk. Consider three examples. First, it appears to many of us that speakers who express systematically divergent ethical views are often thereby engaged in genuine disagreement, rather than merely talking past each other. One natural attempt to explain this appearance involves answering the first Group 3 question by claiming that simple ethical sentences express genuine beliefs about a shared factual subject matter. If correct, this would help to vindicate the appearance of genuine ethical disagreement, because conflicting beliefs about a single matter of fact constitute a paradigmatic form of genuine disagreement. Second, consider the range of distinctive roles that ethical thoughts appear to play in deliberation and action. For example, when someone sincerely judges that she ought to perform an action, we typically expect that she will perform it, if given the opportunity. One natural way to explain this would involve answering the second Group 3 question by claiming that ethical judgments necessarily motivate. Because motivation is central to the explanation of action, this view could help to explain why we expect that people will act on their ethical judgments. Third, consider the appearance that we have considerable ethical knowledge. Answering the third and fourth Group 3 questions by claiming that there are ethical facts, and that armchair reflection can provide knowledge of those facts would be natural components of a theory that attempted to vindicate this third appearance.

4 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 4 The three apparent features of ethical thought and talk just mentioned are instances of the three sets of puzzles about shared ethical subject-matter, the practicality of ethics, and ethical knowledge that Mark van Roojen (2015, chs. 2-4) plausibly claims are central to contemporary metaethics. As van Roojen points out, most systematic metaethical theories will aim to address each of these sets of puzzles. One way to do this is to offer explanations intended to vindicate the relevant appearances. (Our examples were the beginnings of such vindicating explanations.) However, it is also possible to respond to these puzzles by attempting to explain away the apparent feature in question, purporting to show it to be misleading. For example, someone who denied that armchair reflection could provide ethical knowledge might seek to offer a compelling explanation of why we are tempted to believe we have such knowledge. These examples suggest that answers to the paradigmatic Group 3 questions can be used to naturally address certain explanatory concerns. We claim further that what unifies these questions is a distinctive explanatory aim. Our account (which draws on the view developed in McPherson 2012 and Plunkett and Shapiro manuscript) proposes that we can understand what metaethics is in terms of this explanatory aim: Metaethics Metaethics is that theoretical activity which aims to explain how actual ethical thought and talk and what (if anything) that thought and talk is distinctively about fits into reality. The next section will unpack the many moving parts of this account. However, even before clarifying the details, it should be plausible that this account provides a unifying explanation of the significance of the three appearances mentioned above. Genuine ethical disagreement is a central apparent feature of actual ethical thought and talk, as is the range of distinctive roles that ethical judgments appear to play in deliberation. And the appearance that we have considerable ethical knowledge is a central aspect of the apparent relationship between ethical thought and talk on the one hand, and what that thought and talk is about, on the other.

5 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 5 This account also suggests a clear way of explaining the contrast between metaethics and normative and applied ethics. For those projects can themselves be understood as each having a characteristic and distinct explanatory aim. Roughly, these projects aim to explain what we ought to do, either in specific salient clusters of contexts (applied ethics), or with maximal explanatory generality (systematic normative ethics). The success-conditions of these projects, in short, concern getting it right about issues within ethics 1.1 Explaining the Account We now explain each element of our account of metaethics. Before we proceed, however, it will be useful to flag a central element of our approach. Many of the terms we use in our account of metaethics are themselves the sites of intense metaethical controversy. To gloss these terms too precisely would thus be an attempt to adjudicate central metaethical debates. Because our aim here is to illuminate the nature of the metaethical project, we will aim as much as possible to avoid such adjudication. The result is that our account of the explanatory project that unifies metaethics is a schematic one. We take this to be a virtue of our account: we think that metaethics is a project that can be pursued in many different ways, depending especially on one s commitments in other areas of philosophy such as the philosophy of language, metaphysics, epistemology, etc. In light of this, we will typically aim to orient the reader to our way of understanding metaethics by offering paradigm cases of the notions that we deploy. We begin in this spirit by considering our account s focus on ethical thought and talk. Paradigms of ethical thought and talk include the Group 1 and Group 2 questions mentioned in the Introduction (the questions in applied ethics and normative ethics), together with thought and talk that directly answers those questions. It also includes thinking or uttering prosaic claims like embezzling is unethical or you ought to call your friend back tonight. (We return to the issue of characterizing the ethical in 2.3.)

6 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 6 Next consider the account s focus on ethical thought and talk. It is common for much of metaethics to focus narrowly here: for example, to provide an account of the meaning of the term ethically good, or of what it is to have the thought that an action is right. While such a narrow focus may be useful for some purposes, ethical thought and talk as we are understanding it includes much else, including a range of kinds of ethical expressions (beyond ethically good ) and a range of ethical thoughts (beyond those about which actions are right). Moreover, it is worth underscoring here that we take it to include patterns of ethical discourse and reasoning, and (if there are such things) presentational and emotional states that have ethical content. Our reference to actual ethical thought and talk identifies metaethics as a hermeneutic or interpretative project. Metaethics is about the sort of ethical thought and talk that people actually engage in including those parts that we might come to think are mistaken, unfortunate, or misguided. This characterization reflects an important feature of much metaethical practice. Consider two examples: First, one core metaethical question is whether and under what conditions people are motivated by their ethical judgments (see David Faraci and Tristram McPherson s chapter Ethical Judgment and Motivation ). This is a question about the connection between actual patterns of ethical thought and motivation, rather than those we might wish for. Second, an important research program in metaethics is error theory. Error theorists claim that our actual ethical thought and talk commit us to some sort of objectionable error, such as belief in things that do not exist (see Jonas Olson s chapter Error Theory ). Our reference to actual thought and talk is intended to bring out the hermeneutic character of the project as illustrated by these examples, and not (for example) to stipulate that metaethicists ignore counterfactual instances of ordinary ethical thought and talk. Because we understand metaethics as a hermeneutic project, we distinguish metaethics from certain projects that aim to reform or replace our use of expressions like ethically right or ethical obligation. For example, some error theorists think that while ethical talk commits one to false metaphysical views, it nonetheless plays certain important functions in our lives. Some of these philosophers propose replacing our existing ethical thought and talk to eliminate the errors but retain the functional benefits (see the

7 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 7 discussion of revolutionary fictionalism in Richard Joyce s chapter Fictionalism in Metaethics ). One might also advocate reforming ethical thought and talk even if you thought it involved no metaphysical error. For example, one might think that reforming it would promote important practical goals, like social justice, or that reforming it would allow us to more smoothly accomplish our epistemic goals. Influential work that explicitly aims to reform existing understandings of ethics includes Brandt 1979/1998 and Railton Reforming projects like these involve asking normative questions about which concepts we should use, and not just descriptive questions about the ones we do use. (Such normative questions about thought and talk are what Alexis Burgess and David Plunkett dub questions in conceptual ethics. See Burgess and Plunkett 2013a, 2013b.) Ethical thought and talk appears to be about certain distinctive things, such as ethical fact, properties, and relations. Consider a paradigmatic example: some ethical sentences are about what agents are ethically obligated to do. Such sentences are about agents and actions, but what makes them distinctively ethical is the ethical feature ethical obligation that they are about. The sense of aboutness we have in mind here is intensional: compare the way that the name Pegasus is about a winged horse. As this example illustrates, ethical thought and talk might be in this sense about certain things without referring to anything that actually exists. Most views in contemporary metaethics take ethical thought and talk to be about something in some intensional sense, even if only in a minimalist or deflationary one. However, there are some views on which ethical thought and talk is not about anything in even this thin sense. (Some views on which ethical words or concepts are too defective to generate intensions have this implication, as do some non-cognitivist views; see Matt Bedke s chapter Cognitivism and Noncognitivism for discussion.) This is why we say the explanatory task of metaethics partly concerns what ethical thought and talk is about, if that thought and talk is about anything. Our account is intended to be neutral concerning whether ethical thought and talk is about anything, since this is a point of live metaethical controversy. Just as with the other notions involved in our account of metaethics, we intend an ecumenical gloss on explaining, reality, and fitting in. As with ethical, the

8 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 8 interpretation of these terms is a controversial moving part in central metaethical debates. For example, explanatory ambitions are ubiquitous in philosophy, but the relevant notion of explanation can be understood variously in pragmatic terms, in terms of entailment, or in terms of a variety of asymmetric metaphysical relations. Similarly, there are a variety of importantly different philosophical conceptions of reality. These include glosses in terms of what is or what is actual (contrasted in Quine s canonical (1948)), and others which associate it with what is fundamental (e.g. Fine 2001). Different views on these topics will naturally lead to slightly differing ambitions for metaethics, but our characterization of metaethics treats it as compatible with various resolutions of these debates. We can say a bit more about the notion of fitting in. As Frank Jackson says, we expect our best account of the world to be more than just a big list of what there is; we expect it to include some account of how different elements of reality relate to each other (1998, 5). For example, Jackson thinks that this account should feature basic and non-basic ingredients, together with a story about how these relate to each other. In this spirit, we can think of metaethics as attempting to spell out how ethical thought and talk and what (if anything) such thought and talk is about relate to each other and to the relevant other elements of reality. Note that one way that ethical reality could fit into reality could include some elements of ethical reality being among the basic ingredients of reality. Jackson s particular story, both about which elements are basic, and about how such fitting in should proceed is highly controversial: for example, his approach is based on a cognitivist understanding of the parts of thought and talk he is concerned with, and makes extensive use of a particular version of conceptual analysis. We intend the fitting into locution to connect to the broad aims we can recognize in Jackson s work, while abstracting as much as possible from his controversial views about how to realize those aims. On our account, metaethics is a theoretical activity characterized by its aim. Our talk of aims here should be understood in terms of success conditions: those conditions such that

9 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 9 the activity qua that activity counts as successful. This is the sense in which an instance of chess-playing is successful if it concludes in one s victory. Thus, on our view, metaethical theorizing is successful insofar as, and to the extent that, it explains how actual ethical thought and talk and what (if anything) that thought and talk is about fits into reality. In what follows, for ease of presentation, we will sometimes gloss our view of metaethics as follows: metaethics aims to explain how ethical thought, talk, and reality fit into reality overall. This brings in the idea of ethical reality. As we understand it, ethical reality is that part of reality which ethical thought and talk is about. We want to emphasize that this gloss of metaethics be understood purely as a slightly misleading gloss on the official account we have spelled out in this section. For clarity, let us briefly mention three ways in which this gloss might be misleading. First, it elides our emphasis on actual (as opposed to reformed) ethical thought and talk. Second, it replaces our official talk of what if anything ethical thought and talk is about with talk of ethical reality. This might seem to presuppose (controversially) that there is some ethical reality. For example, on an actuality gloss on reality, it might seem to presuppose that some ethical properties or relations are actually instantiated. Third, given our gloss on about above (where we emphasized that it is an intensional notion of about we have in mind), ethical reality will on many accounts of reality and intentionality be considerably narrower than what ethical thought and talk is distinctively about. We hope that, where it is important to do so, readers will read our official account back into the pithy gloss, rather than being misled by the latter. 1.2 An Illustrative Example: Simple Subjectivism If you are reading this paper, you have likely heard of simple subjectivism. Most philosophers working in contemporary metaethics take the view to be indefensible. However, in virtue of its simplicity, it serves as a useful example to illustrate our account of metaethics, as well as some of what makes the metaethical project challenging. The core of the view is a partial theory of ethical thought. Roughly:

10 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 10 Simple Subjectivism What it is for someone to judge that something x is good is for that person to believe that she approves of x. Simple Subjectivism proposes an explanation of how a certain type of ethical thought goodness judgments fits into reality. It explains the nature of goodness judgment in terms of belief and approval. With this theory in hand, many questions about how to fit goodness judgments into reality then become natural tasks for our general accounts of the psychological states of belief and approval. As we have emphasized above, there are many sorts of candidate explanatory relations, so the sort of constitutive account offered by Simple Subjectivism is only one possible way that one might seek to fit ethical thought into one s broader theory of mind. Indeed, one could even begin the task of fitting ethical thought into reality by stating that goodness judgment is a primitive and unanalyzable element of reality. A complete theory of fit for such a primitivist account would include things like explanations of how goodness judgments interact with non-ethical thoughts in reasoning and deliberation. Note that a full explanation of how ethical thought as a whole fits into reality would need to address all the many elements of ethical thought beyond goodness judgments. Simple Subjectivism is silent on these further topics. For example, this thesis says nothing about judging something right or virtuous, or about the nature of ethical deliberation. But even setting aside its focus on good, Simple Subjectivism is far from being a complete metaethical theory. Part of fitting ethical thought into reality involves explaining the relationship between ethical thought and talk. It would be natural to extend Simple Subjectivism to address this task. For example, the subjectivist might claim that assertion of sentences of the form x is good conventionally express the psychological state of judging that x is good. This linkage constrains but does not explain how ethical talk fits into reality. So it would be natural for the simple subjectivist to extend her view further to include a consilient semantic

11 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 11 view. For example, she might claim that the semantic content of a sentence of the form x is good is that the speaker of the sentence approves of x. The resulting partial accounts of ethical thought and talk put us into a position to ask how the developing subjectivist theory fits with our more general accounts of assertion and of the relationship between semantic and mental content. One possibility is that the resulting theory is compatible with these accounts being fully general; another is that the theory requires that we give different underlying accounts for assertion and semantics depending on whether they have ethical content. Our developing subjectivist theory is thus far silent concerning ethical reality. It would be natural to augment it with a consilient metaphysical view. For example, the subjectivist might argue that there is a class of properties, good-relative-to-a (good A for brevity). For something x to be good A is for A to approve of x. And for it to be a fact that x is good A just is for it to be a fact that A approves of x. We can further link the metaphysical account to the accounts of thought and talk by adding natural views about truth: for A s judgment that x is good to be true just is for A to approve of x (or equivalently, given our account of ethical properties, for x to be good A ). Similarly, for a sentence of the form x is good to be true just is for the speaker of the sentence to approve of x. It is again worth emphasizing the diversity of ways in which a metaethical theory might propose to fit ethical reality into reality overall. For example, the simple subjectivist s view is naturally glossed as a reductive view. It is plausible that on this account the property good A reduces to the property being approved of by A. Indeed, it is naturally glossed as an account of what goodness is, or, put another way, a real definition of goodness. The account of truth just offered illuminates one way in which ethical thought and talk can fit (or fail to fit) with ethical reality. It also has implications for another sort of fit: epistemological connections between ethical thought and ethical reality (insofar as there is any). This ties into an aspect of metaethics that many people find pre-theoretically gripping: many people are motivated to do metaethics by puzzlement about how or

12 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 12 whether ethical knowledge could be possible (see Matthew Lutz and Jake Ross s chapter Ethical Skepticism ). Our developing version of Simple Subjectivism does not yet include an epistemological account, but it does entail that, if someone tends to judge that x is good when she approves of x, then these judgments will be reliable. This potential to explain how reliability is possible in ordinary circumstances can play an important role in explaining how ethical knowledge is possible (see Joshua Schechter s chapter Explanatory Challenges in Metaethics ). Finally, because ethical truths are, on this account, facts about the agent s own psychology, it may seem plausible that the agent can achieve justified belief or knowledge simply on the basis of intuitive reflection from the armchair (see Elizabeth Tropman s chapter Intuitionism in Moral Epistemology ). We hope that this discussion of Simple Subjectivism and how it can be developed is helpful in at least three ways. First, it helps to illustrate how broadly we are thinking of the task of fitting ethical thought, talk, and reality into reality. Second, it helps to illustrate our core idea that metaethics is a unified theoretical activity. The ways that we developed the initial theory are all recognizable elements of a metaethical theory, which will be familiar to those engaged in contemporary metaethical inquiry. And far from being a random collection of theses about different topics (mental and semantic content, metaphysics and epistemology), the collection of claims that we discussed were recognizably unified, as elements of a candidate partial explanation of how ethical thought, talk, and reality fit into reality. The view we developed is far from complete, but we predict that if you continued to add more features to this theory, aiming to more fully achieve this explanatory aim, those features would continue to be recognizable as elements of a metaethical theory. The version of simple subjectivism developed here is an elegant theory. Moreover, it has a number of features that (at least many) will take be significant points in its favor. Here we mention two. First, consider a variant on a point that we made in 1: when someone sincerely judges that something is ethically good, we ordinarily expect her to be moved to pursue it. Simple Subjectivism can explain this: The judgment that sleep is good is a belief that one approves of sleep, on this account. It is not at all surprising for someone

13 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 13 to be moved to pursue things she approves of. So provided that one is not self-deceived about what one approves of, the account can explain why we expect people to be moved to pursue what they judge to be good. Second, the developed version of the view promises to smoothly integrate ethical thought, talk, and reality into a fully naturalistic account of reality overall. In light of the explanatory power and massive achievements of scientific theorizing, many philosophers take providing a naturalistic metaethical account to be an important goal (see Peter Railton s chapter Naturalistic Realism ). The subjectivist account we sketched also illustrates how challenging metaethical theorizing is. For despite its virtues, this view also faces several deep problems. Consider four examples, each of which is an instance of a broad kind of problem that many systematic metaethical theories face. First, simple forms of subjectivism have difficulty explaining genuine ethical disagreement. For suppose that I think that being vegan is good and you think it is not good. On Simple Subjectivism, my belief concerns my own psychology, and your belief concerns your psychology. This seems at least initially insufficient to constitute genuine disagreement. For our beliefs are about two entirely different things, and, thus, it seems there is no rational conflict between my belief and yours. Second, the view might seem hard to fit with our experience of the deliberative significance of ethical thought: the thought that something is good appears different from the thought that I approve of it; the former thought appears at least on its face more objective and less introspective than the latter (a point emphasized by David Enoch is his chapter Non-naturalistic Realism ). Third, the view seems to yield the wrong extension for the predicate good. In short: most of us think that there can be good things even if we do not currently approve of them. The simple subjectivist picture thus seems to conflict with our substantive views about goodness.

14 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 14 Fourth, the two points just made also have implications for the epistemological plausibility of the view. We often agonize over the considerations that seem to us to be on either side of an issue, while trying to figure out what is good. But if the simple subjectivist picture we sketched were correct, this would be misguided: we should seek instead to simply introspect the truth of the matter. In light of these and other objections, we are inclined to reject the simple subjectivist picture out of hand. But it is worth noting two characteristic and important methodological points here. First, it is open to the subjectivist to seek to debunk some of these appearances: to suggest that they are misleading as characterizations of actual ethical thought and talk. If successful, such a debunking explanation will entail that the appearance in question is no longer a constraint on our seeking to explain how ethical thought, talk, and reality fits into reality. Second, it is natural to ask whether the subjectivist can modify her view in a way that preserves the virtues of the simple view, while avoiding some or all of the objections just identified (to explore contemporary views that can be understood in this way, see Alex Silk s chapter Contextualism and Isidora Stojanovic s chapter Relativism ). In any case, our aim here was to offer a simple instance of metaethical theorizing to exemplify our account of metaethics. We now return to that account. 2. Consequences and Clarifications The preceding section set out the heart of our account of metaethics understood as a theoretical activity. This section develops the account in three ways. First, we explain our assumptions about how our proposal should be assessed. Second, we explain how we think about the relationship between metaethics as an activity, and the idea that certain claims are metaethical claims. Finally, we explain how facts about the connections between different kinds of normative standards (e.g., the standards of morality and practical rationality) matters for metaethics.

15 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics Metaethics as a Theoretical Term A guiding assumption of our project is that metaethics is a theoretical term, and that we should evaluate accounts of metaethics accordingly. Negatively, the meaning of theoretical terms is less beholden to prior usage than ordinary, non-theoretical terms. Consider for example the surprising discoveries that atoms are divisible and that space is not well modeled by Euclidean geometry. Positively, theoretical terms earn their keep either by referring to a theoretically interesting object of inquiry, or by being instrumentally useful to inquiry. While both of these criteria provide some reasons to favor fidelity to existing use, these reasons can be outweighed, as the examples just given suggest. This is especially true if existing use is somewhat heterogeneous (we will see in 3 that this is the case with the term metaethics ), and there is a theoretically illuminating way of regimenting that usage. In the preceding section we emphasized various ways that our account captures core features of existing use. However, if there are apparent intuitive counterexamples to our view, we do not take this to necessarily constitute a serious objection to our account. Depending on one s views about meaning, one may thus want to think of our proposal as providing a reforming definition, in the vein of Richard Brandt (1979/1998) and Peter Railton (1986). However, because metaethics is a term of art, our account may not count as reforming at all: theoretical utility may be a central constraint on the unreformed meaning of this term. It may be worth addressing a potential confusion here. In the previous section, we emphasized that metaethics is a hermeneutic project, which aims to theorize actual ethical thought, talk, and (maybe) reality. This may seem to be in tension with our claim that metaethics is a theoretical term. An analogy shows that it is not: adverb of quantification is a theoretical term from semantics, which earns its keep in virtue of its role in helping semanticists explain actual linguistic patterns. Terms that we introduce (or reform) in the process of doing metaethics and, on our view, metaethics itself should be understood in the same basic way: namely, as earning their keep in virtue of their role in a significant theoretical project.

16 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 16 A second implication of our account concerns the significance of metaethics. We have occasionally encountered the assumption that the term metaethics denotes inquiry that is somehow deserving of more attention, deeper, or more properly philosophical than issues within normative and applied ethics. Our characterization of metaethics as a theoretical term rests in part upon the idea that metaethics is an important theoretical activity. However, it does not imply the comparative judgment just mentioned. We think the comparative judgment is too sporadic to count as a conventional presupposition of the word metaethics, but if it were, this would be one way that our account would reform existing usage. We think the comparative judgment is simply false: there are many philosophically deep and important issues within ethics itself, including the very applied ends of the field. Our account, however, is neutral with respect to this kind of comparative judgment: it would make little sense to build controversial judgments of comparative importance into our account of a theoretical notion. A third implication of our account concerns fundamental vs. non-fundamental metaethics. One common pattern in metaethics is for a theorist to identify what she takes to be the most fundamental explanandum in the area perhaps value, or ought, or reasons, and perhaps with a focus on concepts first, or language, or properties and then to focus her metaethical investigations on this target. (For example, our exposition of Simple Subjectivism focused on judging something to be good.) If there is an explanatorily basic ethical concept (or property, or relation ), then this might well be a sensible strategy. On the one hand, such an account might at least suggest illuminating answers to certain general metaethical questions. And on the other, an account of the basic concept (or property, or relation, ) might put us in an excellent position to extend our metaethical theory to non-basic explananda. On our account, however, this is at most a strategic point: even if it turns out that there really is some fundamental, explanatorily basic ethical concept (or term, or property), the non-basic explananda are still part of metaethics. Non-basic ethical thought, talk, and reality are parts of ethical thought, talk, and reality, and hence part of the explanatory purview of metaethics as we understand it. Such strategic considerations aside, non-basic explananda may be at least as worthy of attention as the basic explananda.

17 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics Metaethics as an Activity, and Metaethical Claims Our discussion of Simple Subjectivism sought to illustrate the point that metaethics can be well-understood as an activity with the aim of explaining how ethical thought, talk, and reality fit into reality. This section explain how we understand the relationship between the metaethical activity and this aim, and between metaethical activity and metaethical claims. To begin, notice that someone could seemingly make important contributions to metaethics without explicitly endorsing the aim that we identify. This is especially plausible when we consider a philosopher who is dedicated to working out the nuances of some specific problem, as opposed to building a comprehensive account of ethical thought, talk, and reality. This is possible, we suggest, because metaethics is a collective theoretical project: the kind of scope and unity suggested by our discussion of simple subjectivism need not be exemplified in the work of a single individual, but can instead be characteristic of a theoretical pattern that emerges from the work of many. The nuance-focused philosopher can count as doing metaethics in virtue of the relationship of her work to this collective project. Because of this, someone could contribute substantively to this project without thinking of herself as contributing to it, or even conceiving of the project as such. Consider next how this collective project is organized. In expository work on metaethics, it is common to regiment metaethical views into broad clusters such as naturalistic realism, expressivism, etc. (we follow this common practice in Part I of this volume). We think it is useful to think of these clusters as research programs: families of views, each of which aims to systematically explain how ethical thought and talk and what (if anything) such thought and talk is about fits into reality overall. Within each of these research programs, there are certain theses and patterns of explanation that help make it a recognizable type of approach to the explanatory project of metaethics. And within each of these research programs, philosophers direct a great deal of constructive and critical attention to debating the elements of specific systematic and

18 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 18 comprehensive metaethical views. This activity can be understood as attempting to identify the overall theory that best realizes the overall research program. An example here might help. Consider a classic kind of non-naturalistic realist view in metaethics. This sort of view characteristically accepts the metaphysical thesis that the fundamental ethical facts (or truths or properties) are sui generis. This might be cashed out in a variety of ways: e.g., the real definition of ethical facts cannot be given in fully non-normative terms, or that the fundamental ethical facts are ungrounded in any other kind of fact (whether naturalistic ones, such as facts about how human brains work, or super-naturalistic ones, such as facts about God). This sort of metaphysical view fits smoothly with certain claims about ethical thought and talk. For example, nonnaturalists typically accepts some form of cognitivism at the level of ethical thought, according to which, roughly, ethical judgments are beliefs (see Bedke s chapter Cognitivism and Non-cognitivism ). Non-naturalists typically pair this with a commitment to descriptivism about ethical talk, according to which, roughly, the meaning of ethical terms are to be understood in terms of their contribution to the truthconditions of the sentences in which they occur. Finally, non-naturalists typically embrace some kind of intuitionism in moral epistemology. Especially ambitious nonnaturalists try to defend a relatively comprehensive package that includes claims about these and many other topics (e.g Shafer-Landau 2003, Enoch 2011). However, many more philosophers contribute to the research program of non-naturalistic realism without ever developing such a package. Our proposal gives a unified and fundamental account of what the metaethical project is. This leaves open the question of what makes a claim metaethical. We think the idea of a metaethical claim is less philosophically illuminating than that of the metaethical project as such. We here favor a pluralist, context-sensitive account. The basic idea of our account is that we can identify a number of different salient ways in which an individual claim or thesis can be related to the metaethical project. In different contexts, it can be philosophically helpful to focus on one or another of these relations. For example, a claim might be a key part of a certain attempted metaethical

19 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 19 explanation. Or it might be something that, if true, would entail that this metaethical explanation is incorrect. We could also choose to focus on a claim s relation to a specific metaethical theory, or to all possible such theories, or to those theories that are currently considered live options, etc. We think there are a variety of sensible uses of metaethical claim that align with each of these options, and that none of them is clearly more theoretically useful than the others. In different contexts, different of these relations, and different given attempts to do metaethics, will be more or less salient. We thus think that metaethical claim can usefully be treated as a context-sensitive term that picks out different things in different contexts, depending on what is most salient in that context. We would offer a similar contextualist account concerning what counts as a metaethical question or a metaethical controversy, etc. One important motivation for the contextualist account just offered is that certain claims play a central role in some metaethical projects but not in others. In order to drive this point home, we will discuss an example in some detail. Consider the claim that the fundamental ethical facts are dependent on our mental states. Call this thesis mind-dependence (for a more detailed discussion, see Connie Rosati s chapter Mind- Dependence ). One clear example of mind-dependence was offered by our extended version of simple subjectivism. On this view, goodness facts depend on certain mental facts: for it to be a fact that x is good A just is for it to be a fact that A approves of x. It is tempting to take the question of whether ethical facts are mind-dependent to be a paradigmatic and central metaethical question. However, this becomes much less clear when we consider a paradigmatic metaethical research program: expressivism. On one rough gloss, metaethical expressivism can be understood as the conjunction of three claims: a) Ethical judgments consist, at the most basic explanatory level, in some kind of non-cognitive attitude (e.g., desires or plans); b) Ethical statements statements in language which communicate those judgments consist of expression of the relevant non-cognitive attitude, rather than (e.g.) of the belief that one has that non-cognitive attitude; and c) the meaning of those ethical statements is to be understood or explained in terms of such expression. (For a more detailed discussion, see the Elisabeth Camp s chapter Expressivism.) By itself, the truth of expressivism which is a thesis about

20 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 20 ethical thought and talk doesn t settle whether or not mind-dependence about ethical facts (or properties, truths, etc.) is correct or not. However, within the contemporary research program, expressivism is typically coupled with significant attempts to interpret our talk of ethical reality. (This is another example of the way that metaethical research programs tend to aim explain how ethical thought, talk, and reality fit into reality overall.) It is instructive to consider the implications of two such attempts. A classic kind of anti-realist expressivist (e.g. Ayer 1936/1952) argues that the expressivist account of thought and talk is inconsistent with positing ethical truths, facts, or properties. Such posits would rest on false presuppositions, on this view. Compare: I say Hooray for bears!, thereby expressing my approval of our ursine cousins. It would betray confusion for you to say: Is that a fact? ; this question would rest on an obviously false presupposition. The question of mind-dependence purports to concern ethical facts. Far from being a central metaethical question, this question thus likewise rests on a false presupposition, according to the anti-realist expressivist. Consider next one form of quasi-realism, which explains our entitlement to utter claims about facts, mind-independence, and the like by appealing to minimalist theories of locutions like fact and mind-independent. On such theories, the meaning of these expressions is exhausted by certain equivalence schemas. For example, the meaning of It is a mind-independent fact that it is wrong to eat bears might be claimed to be roughly equivalent to that of Hooray for not eating bears, whatever anyone thinks about doing so! (We say roughly because the meaning of the two sentences cannot be exactly equivalent; the first sentence has compositional properties the second lacks.) Importantly, on this view, the latter sentence is the more explanatorily illuminating of the two. So on this view, the question of mind-independence simply does not arise at the level on which we aim to explain how ethical thought and talk and what (if anything) such thought and talk is about fits into reality overall. Rather, on this kind of quasi-realism, mind-dependence or mind-independence can be understood as shorthand ways of describing the modal structure of certain patterns of substantive ethical commitment. In short, the issue is whether to say things like Hooray for φ-ing, whatever anyone thinks about φ-ing or not. (See Terence Cuneo s chapter Quasi-

21 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 21 Realism for discussion.) Many quasi-realist expressivists are drawn to their view in part because it gives them the resources to endorse mind-independence, which they take to be an attractive substantive ethical position on independent grounds. But it might well be that this is a mistaken substantive ethical commitment on their part, and that quasirealists should endorse mind-dependence instead. (For discussion, see Street 2011.) These examples show that the thesis of mind-dependence is a central element of some metaethical theories (such as simple subjectivism), rests on a false presupposition according to others (such as anti-realist expressivism), and is better understood as a substantive ethical claim according to others (such as one prominent form of quasirealist expressivism). In light of this, there are many contexts where it will make sense to count mind-dependence as a metaethical issue (hence our including a chapter on it in this volume), but there are other contexts where this could be unproductive or misleading. Our general point about metaethical claims can also be illustrated by considering philosophical theses and issues which, by themselves, seemingly have little to do with ethics. For example, consider issues about the semantics of conditionals, or about real definition. On our view, tackling such issues might be crucial to certain research programs in metaethics, and irrelevant to others. Understanding the semantic properties of conditionals might be crucial to assessing the Frege-Geach problem for expressivism (see Jack Woods s chapter The Frege-Geach Problem ). And understanding real definition might be crucial to assessing certain forms of realism (see Gideon Rosen s chapter Metaphysical Relations in Metaethics ). It seems to us unproductive to try to settle in a context-independent way whether claims about conditionals or about essence are metaethical or not. We think it is more illuminating to put the characteristic explanatory activity at the center of our understanding of metaethics. There is no principled limit to the sorts of claims or questions that might be central to some or another metaethical research program. This includes traditionally philosophical claims and questions, but also issues in other fields, such as anthropology, sociology, cognitive science, linguistics, and

22 McPherson and Plunkett: The Nature and Explanatory Ambitions of Metaethics 22 psychology. In some contexts it might be useful to pick out certain core issues that are pressing for many different promising contemporary attempts to carry out the metaethical project, and label these central metaethical issues. But there is nothing particularly deep about this: in other contexts, it will be important to expand or contract that list in order to focus on those issues that will help us to make progress on the metaethical project. 2.3 Ethics, Morality, and Robust Normativity Our gloss on metaethics characterizes it as an explanatory project concerning actual ethical thought, talk, and reality. However, self-described metaethical practice has a variety of explanatory targets, so in this section we return to this issue in more detail. (Readers of the volume will notice that the volume as a whole varies a lot on this front, with some chapters focused more broadly on the normative, and others more narrowly on the moral.) We take metaethics to concern ethical thought, talk, and reality. Roughly, ethical questions concern how to live or act. The purview of ethics is thus at least at first blush broader than that of morality. For example, one might engage in extended and careful deliberation in choosing between two professions that one takes to be equally morally acceptable, or one might wonder what color socks to wear to work today. These are questions about what to do, but not moral questions in any obvious sense. (For an illuminating discussion, see Stephen Darwall s chapter Ethics and Morality.) It is common to distinguish between two branches of the normative: the evaluative and the deontic (which is also sometimes called the narrowly normative ). For example, good and bad are paradigmatic evaluative terms, while ought and should and permissible are paradigmatic deontic terms. And there are other normative categories, such as the reason relation, which do not fit neatly into either group. We take the ethical/moral distinction to cross-cut all of these distinctions. For example, it might be that in the first scenario imagined in the preceding paragraph, one has most ethical reason, but not most moral reason to choose one profession over the other. Perhaps this is because considerations of prudence or self-interest favor the first profession, in a way
